Feature Request - Create Unique File - "copy" Alternative?

It would be really handy if we could adjust the way files are named by the Create Unique File action.

Currently, if MyFile.txt exists, MyFile copy 1.txt will be created.

It would be nice if it were possible to specify the word before the incremented number, like this:

MyFile 1.txt
MyFile version 1.txt
MyFile v1.txt
MyFile Alternative 1.txt
